Refer to the Minitab printout regarding prehistoric pottery.

(a) The standard error S_e of the linear regression model is given in the print out as “S.” What is the value of S_e?

(b) The standard error of the coefficient of the predictor variable is found under “SE Coef.” Recall that the standard error for b

From the Minitab display, what is the value of the standard error for the slope b’?

(c) The formula for the margin of error E for a c% con­fidence interval for the slope β can be written as E = t_c(SE Coef). The Minitab display is based on n = 9 data pairs. Find the critical value t_c for a 95% confi­dence interval in Table 6 of Appendix II. Then fi­nd a 95% confidence interval for the population slope β.
